Re: 1996 reinell 184brxl fuel guage only registers from half full and down
It sounds like there may be a problem with the sending unit. The sending unit shoulg have a float of sorts that rises and falls with the fuel level. If you can get to it, you might check to make sure there's not something keeping that float from reaching the top of the tank when it's full. If it is, there may be something more wrong with the sending unit itself.
That said, it is probably smart to rule out your gauge first as a problem down in the tank will be much harder to deal with. You could order a cheap replacement fuel gauge and install it. If it fixes it, you're done! If it does the same thing, you know the problem is down in the tank in the sending unit. You can just return the gauge at that point and concentrate on the real problem.
